Is Sipile an IQ tax?

The hole-in-the-hole pens that are very popular on the market are also the first inventions of Sipelajia, so I bought both of them all in!

This hole-dong pen has a triangular pen holder! The body of the pen is designed with many small holes, but the function of these holes is not simple!

The ergonomically designed oval holes are cleverly rotated at an angle of 30°. Each hole has a diameter of more than 10mm and fits the child's fingers perfectly, allowing the child to hold the pen correctly. The posture makes it easy to write~

I think the design is also considerate. The anti-bite lead-free area at the end of the pen is the best for children who love to bite pencils. Safety and health? A pencil? Don’t just look at its price, you must first pay attention to the value it brings! It can help children hold pens correctly to prevent hand deformities and avoid myopia and hunchback! So Sipile is really not an IQ tax?
